Background: It is now generally accepted that an active lifestyle is beneficial for cognition, but can these benefits be transmitted for the active pregnant woman to her unborn child? This has been demonstrated in rats where the pups born of mothers who exercised during pregnancy had increased hippocampal neurogenesis and better memory and learning capabilities. Human studies tend to confirm this by looking at behavioral results, ie. better orientation and state regulation skills in newborns. The aim of the present study is to verify this on the electrophysiological level and to determine the effects of an active lifestyle during pregnancy on the newborn's brain development.
